Antioxidative, antifungal, cytotoxic and antineurodegenerative activity of selected Trametes species from Serbia
(Public Library Science, San Francisco, 2018)
In a last few decades mushrooms are increasingly attracting attention as functional food and sources of biologically active compounds. Several Trametes species have been used for centuries in traditional medicine of East ...
Electrochemical synthesis of nanosized hydroxyapatite/graphene composite powder
(Springer Japan Kk, Tokyo, 2015)
Electrochemical synthesis was employed to prepare a novel hydroxyapatite/graphene (HAP/Gr) composite powder suitable for medical applications as a hard tissue implant (scaffold). The synthesis was performed in a homogeneous ...
Antioxidants of Edible Mushrooms
(MDPI, Basel, 2015)
Oxidative stress caused by an imbalanced metabolism and an excess of reactive oxygen species (ROS) lead to a range of health disorders in humans. Our endogenous antioxidant defense mechanisms and our dietary intake of ...
Nimonic 263 microstructure and surface characterization after laser shock peening
(Croatian Metallurgical Soc, Zagreb, 2015)
The Laser Shock Peening (LSP) is applied to the surface of Nimonic 263 alloy. The changes in microstructure and surface topography are observed and analyzed by Scanning Electron Microscopy (SEM), profilometer and microhardness ...
Thermal, Ceramic and Technological Properties of Clays used in Production of Roofing Tiles – Principal Component Analysis
(International Institute for the Science of Sintering, 2018)
This research describes a study of 11 selected samples of brick clays applied in roofing tile production, by using simultaneous thermal analysis. Additionally, the laboratory-sized samples were prepared and fired (850-950 ...
Hydrometallurgical recovery of tin and lead from waste printed circuit boards (wpcbs): limitations and opportunities
(Croatian Metallurgical Soc, Zagreb, 2016)
In this paper, possibility for selective Pb and Sn recovery, using three different solutions of NaOH, HCl and HNO3, from WPCBs containing low concentrations of Pb and Sn is presented. According to obtained results, over ...
Modeling of the Mechanical Behavior of Fiber-Reinforced Ceramic Composites Using Finite Element Method (FEM)
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
Modeling of the mechanical behavior of fiber-reinforced ceramic matrix composites (CMC) is presented by the example of Al2O3 fibers in an alumina based matrix. The starting point of the modeling is a substructure (elementary ...
The advantages of using activated flux-cored wire compared to solid wire in the mag welding process from the aspect of metallurgical characteristics
(Croatian Metallurgical Soc, Zagreb, 2014)
This paper analyzes, from the metallurgical aspect, the quality of the new flux-cored wire intended for the MAG welding process in function of changes in shielding gas composition and changes in welding parameters. The ...
Heat generation during plunge stage in friction stir welding
(Vinca Institute of Nuclear Sciences, 2013)
This paper deals with the heat generation in the Al alloy Al2024-T3 plate under different rotating speeds and plunge speeds during the plunge stage of friction stir welding. A 3-D finite element model is developed in the ...
Comparison of Mechanical Behavior of SiC Sintered Specimen to Analysis of Surface Defects
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
Silicon carbide is the material that in sintered form is suiTab. for protection from impact as part of the multilayered structure. Its role is to accumulate energy from the projectile, to plastically deform the projectile ...
